提出一种将局部均衡模型与一般均衡框架结合的方法，在关税细目层面分析全球乳制品自由化，揭示标准一般均衡分析中的加总误差。
Abstract General equilibrium (GE) models have been criticized because of policy aggregation issues. Partial equilibrium (PE) models can be more disaggregated but do not account for the economy‐wide effects from trade reform. In this article, we illustrate a methodology that combines a fully disaggregated, subsector (PE) model with a standard GE framework permitting us to extend GE analysis to the tariff line. We offer some insight into the aggregation errors implicit in standard GE analyses by comparing our PE/GE approach to that of GE only under a global dairy liberalization experiment. Our PE/GE approach allows for a comprehensive treatment of tariff rate quotas at the sub‐sector level across narrowly defined product lines.
